HYR451T Water-Saving Toilet Total Repair Kit with Dual Flush Valve

The HYR451T combines two products that will increase your toilet’s efficiency and save water and money. No leaky flapper, tangled chain or handle that has to be jiggled. The Total Repair Dual Flush Valve quickly and easily converts most standard 2-piece toilets 1.6 GPF and higher into a two-handle, dual flush toilet. The short center lever is the Quick Flush setting that uses significantly lower water volumes for liquids and paper – the setting needed 4 out of 5 times. The second complete push lever at end is the Full Flush that uses the normal amount of water for solids. Designed for drop-in installation, the HYR451T can be installed without tools and without having to remove the tank. The Total Repair Kit can be calibrated to adjust the exact amount of water needed and detects leaks.

Installed hydro clean valve a little over a year ago. Installation went very easy, anyone that can follow simple printed instructions can do in about 45 minutes. For the first year it performed flawlessly and saved us a ton of money on water bills. However in the last ...Read More2 months or longer the tank flapper stays stuck in the open position occasionally ( more than not), this made my water bill sky rocket. Says somewhere in the literature that it will detect leaks, must be a silent alarm as i did not know it was sticking until very recently, ( actually i heard the water going thru the drain pipe in the basement). I have no idea how long unit has been malfunctioning and blamed the high usage on showers and other items like washing clothes. I now know that was not the case as we did not increase our other water usages and had me scratching my head as to why the water bills had jumped so high. Based on this failure, i would not recommend this product to anyone, and if you install one, watch it closely for the flapper stop to seal.

I installed this dual flush valve and the Hydroclean fill valve in 3 toilets about 6 years ago. All had been working flawlessly until recently one of the flush valves would not do the quick flush unless we held the button in. I tried the troubleshooting tips but that did not...Read More fix it. The valves sold back then had a 5 year warranty. I called technical support to see if there was anything else I could try before buying a new valve. The technical support rep told me that I had already tried everything he would have suggested and offered to send me a new valve free of charge. I told him I did not expect this since the valve was out of warranty. About a week later the valve showed up at my door. I installed it and it works fine. You can’t go wrong with these valves and this company. I have been very happy with the operation of the valves and have saved a lot of water considering most of one’s flushes are the quick flush. I am overjoyed with the customer service.
